Order of Operations

Front

What is the Order of Operations in mathematics?

Back

The Order of Operations is a set of rules that dictates the sequence in which calculations are performed in a mathematical expression. The acronym PEMDAS is often used to remember the order: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).

How do you solve an expression with parentheses?

Back

You solve expressions with parentheses first, calculating the value inside the parentheses before applying any other operations.

What is the result of the expression 5x(6-3)?

Back

The result is 15, calculated as 5 times the result of (6-3), which is 3.

Front

What is the result of the expression (24 - 16) ÷ 8?

Back

The result is 1, calculated as (24 - 16) equals 8, and then 8 ÷ 8 equals 1.

Front

What is the result of the expression (6 + 2) x (3 + 2)?

Back

The result is 40, calculated as (6 + 2) equals 8 and (3 + 2) equals 5, then 8 x 5 equals 40.

In the expression 13[7.9 + 4(2.3)], which operation should be performed first?

Back

The operation 4(2.3) should be performed first, as it is inside the parentheses.

Front

What is the result of the expression 3(2)?

Back

The result is 6, calculated as 3 times 2.

Front

Why is it important to follow the Order of Operations?

Back

Following the Order of Operations is crucial to ensure that mathematical expressions are solved correctly and consistently.

Front

What is the difference between multiplication and division in the Order of Operations?

Back

Multiplication and division are performed from left to right, meaning that if both operations appear in an expression, you perform them in the order they appear.
